This invention relates to improvements in window ventilators, and has for one of its objects to provide an improved ventila tor of simple, practical and economical con- 1 5 struction wherein the rclosure-member which is pivoted to the framev of the ventilator may be adjusted Vto variousr open positions i relative'to said frame and frictionally held. vin suchpositions by end sections extending- Another object is to so connect the end sections of the closure member thereto that said sections can be moved'k to Aa folded or inoperative .position between the closure 15 member and supporting rameto better enable the ventilator to ybe transported or stored when not in use. Y y i A further object is to provide the supporting or main frame of the ventilator v` 20 with longitudinally adjustable end portions which will enable the frame to be fittedl into window frames of various widths.

Thejabove andvother objects will appear more clearly from the following de-y 25 tailedv description, when taken in Yconnection ywith the accompanyingv drawings, which illustrate a preferred embodiment of the inventive idea. f '-.In the drawingsu j y so Figure 1 is a front elevation of the ventilator with the parts in folded or inoperative position; y

Figure 4 is a front elevation wlth the clo surefmember opened; -v y Figures 5 and 6 are vertical sections showing, respectively, the closure. member in open and closed positions; and j Figure 7 is an enlarged fragmentary front elevation, partlyV broken awayN and shown '45 in section. l

Referring moreV particularly to .the accompanying drawings, the numeral 10 indi- Cates the main or supporting frame for .the ventilator and is adapted to be positioned '356 vertically in a window: frame, as shown inY Figure `2,l the upper.v edge of.L the Qframe` 10 l u Atheirame l10 sogas to fit .into window 'v frames of'diferent sizes,` each endof the frame 10 isprovided rwith-a longitudinally adjustable end member. 13.
